Ukuhlaziywa kwesibonelo sezinhlelo zokusebenza zokushisela i-laser ezinobubanzi obuhlukene bomnyombo

Usayizi wobubanzi be-laser core uzothinta ukulahleka kokudlulisela kanye nokusatshalaliswa kokukhanya kwamandla.Ukukhetha okunengqondo kwe-diameter eyinhloko kubaluleke kakhulu.Ububanzi bomgogodla owedlulele buzoholela ekuhlanekeni kwemodi kanye nokusakazeka ekudluliselweni kwe-laser, kuthinte ikhwalithi ye-beam kanye nokunemba kokugxila.I-diameter eyinhloko encane kakhulu izobangela Ukulinganisa kwamandla okukhanya kwe-fiber yemodi eyodwa kuba kubi kakhulu, okungahambisani nokudluliswa kwe-laser yamandla aphezulu.

1. Izinzuzo kanye nokusetshenziswa kwama-laser amancane amaphakathi (<100um)

Izinto ezikhanyayo kakhulu: i-aluminium, ithusi, insimbi engagqwali, i-nickel, i-molybdenum, njll.;

(1）Izinto ezibonisa ukukhanya kakhulu zidinga ukukhetha i-laser encane yobubanzi obuphakathi.I-laser density high power beam isetshenziselwa ukushisisa ngokushesha into esetshenziswayo ibe yi-liquefied noma i-vaporized state, ethuthukisa izinga lokumuncwa kwe-laser lento futhi izuze ukucutshungulwa okusebenzayo nokusheshayo.Ukukhetha i-laser enobubanzi obuwumgogodla omkhulu kungaholela kalula ekuboniseni okuphezulu., okuholela ekushiselweni kwe-virtual ngisho nokushiswa kwe-laser;

Izinto ezizwela ukuqhekeka: i-nickel, i-nickel-plated yethusi, i-aluminium, insimbi engagqwali, i-titanium alloy, njll.

Lokhu okuqukethwe ngokuvamile kudinga ukulawulwa okuqinile kwendawo ethinteke ukushisa kanye nechibi elincane lokuncibilika, ngakho-ke kufaneleka kakhulu ukukhetha i-laser encane yobubanzi obuwumgogodla;

Ukucubungula i-laser enesivinini esikhulu:

(3）I-welding yokungena ejulile idinga ukucutshungulwa kwe-laser ngesivinini esikhulu, futhi kuyadingeka ukukhetha i-laser ene-high density yamandla ukuze kuqinisekiswe ukuthi amandla omugqa anele ukuncibilikisa impahla ngesivinini esikhulu, ikakhulukazi i-lap welding, i-welding yokungena, njll., zidinga ukujula kokungena okuphezulu.Kungcono ukukhetha i-laser encane ye-diameter efanelekile.

2. Izinzuzo kanye nokusetshenziswa kwama-lasers amakhulu obubanzi obuyingqikithi (>100um)

Ububanzi bomnyombo omkhulu nendawo enkulu, indawo enkulu embozwa ukushisa, indawo ebanzi yesenzo, kanye nokuncibilika okuncane kuphela kwendawo yezinto ezibonakalayo kufinyelelwa, okulungele kakhulu ukusetshenziswa ekufakweni kwe-laser, ukuncibilika kwe-laser, ukufakwa kwe-laser, ukuqina kwe-laser, njll. lezi zinkambu, indawo enkulu yokukhanya isho ukusebenza kahle okuphezulu kokukhiqiza kanye namaphutha aphansi (i-thermal conductive welding cishe ayinazo iziphambeko).

Ngokuya nge-welding, indawo enkulu isetshenziselwa ikakhulukazi ukushisela okuhlanganisiwe, okusetshenziselwa ukuhlanganiswa ne-laser encane yobubanzi obuphakathi: indawo enkulu yenza ubuso bezinto buncibilike kancane, buguquke busuke buqinile bube oketshezini, okuthuthukisa kakhulu izinga lokumuncwa. Kule nqubo, ngenxa yokushisa kwendawo enkulu, ukucubungula emva kokucubungula, kanye ne-gradient enkulu yokushisa enikezwe ichibi elincibilikisiwe, impahla ayinakho ukukhubazeka okubangelwa ukuqhekeka. ngokufudumeza ngokushesha nokupholisa ngokushesha.Ingenza ukubukeka kwe-weld kube bushelelezi futhi kuzuze i-spatter ephansi kunesixazululo esisodwa se-laser.
